Report calls for urgency on climate change

- JO MOIR

WELLINGTON: New Zealand’s first national climate change risk assessment has identified 10 significan­t areas that need to be urgently addressed by the Government in the next six years.

The risk assessment is an overview of how New Zealand may be affected by climate changerela­ted hazards, and will be used to develop a national adaptation plan over the next two years.

The assessment report, released yesterday, has been done based on a ‘‘highemissi­ons, businessas­usual future, resulting in a projected 67cm sealevel rise and 3degC temperatur­e increase by 2090’’.

Extreme weather events such as storms, heatwaves and heavy rainfall are likely to be more frequent and intense.

Large increases in extreme rainfall are expected everywhere in the country and the number of frost and snow days are projected to decrease, the report says.

The National Climate Change Risk Assessment identified 43 risks that could have a major or extreme consequenc­e to New

Zealand.

Of these, there are 10 risks the reports says require urgent action in the next six years. They are.—

To coastal ecosystems due to sealevel rise and extreme weather events.

To indigenous ecosystems and species from the enhanced spread of invasive species.

To social cohesion and community wellbeing from displaceme­nt.

Of exacerbati­ng existing social inequities and creating new ones due to unequal distributi­on of climate change impacts.

To government­s from economic costs associated with lost productivi­ty, disaster relief expenditur­e and unfunded contingent liabilitie­s.

To the financial system from instabilit­y due to extreme weather events and ongoing, gradual changes.

To potable water supplies, both availabili­ty and quality, due to changes in rainfall, temperatur­es, drought, extreme weather events and ongoing sealevel rise.

To buildings due to extreme weather events, drought, increased fire weather and ongoing sealevel rise.

Of maladaptat­ion due to the applicatio­n of practices, process and tools that do not account for uncertaint­y and change over long timeframes.

That current institutio­nal arrangemen­ts are not fit for climate change adaptation.

There were some opportunit­ies identified as a result of climate change, but the report noted research would need to be done to ensure responses to those opportunit­ies did not worsen climate change impacts unintentio­nally.

The opportunit­ies are higher productivi­ty in some primary sectors due to warmer weather; businesses being able to provide adaptation­related goods and services; lower cold weatherrel­ated mortality, and lower winter heating demand.

Maori will also be disproport­ionately affected, including risks to social, cultural, spiritual and economic wellbeing from loss and degradatio­n of lands and waters, and from loss of species and biodiversi­ty.

They would also face risks to social cohesion and community wellbeing from displaceme­nt of individual­s, families and communitie­s, and risks of exacerbati­ng and creating inequities due to unequal impacts of climate change, the report found.

The Climate Change Response (Zero Carbon) Amendment Act 2019 requires a risk assessment at least every six years.

Climate Change Minister James Shaw said yesterday the report showed ‘‘the progress this Government has made to solve the climate crisis is essential to creating cleaner and safer communitie­s across New Zealand’’.

‘‘Because of this report, we can see clearer than ever that the action our Government is taking to reduce emissions is essential for making sure we pass on a safer planet to our children and grandchild­ren.’’

Many of the risks we now faced could be traced back to the failure of previous government­s to take meaningful action to cut our emissions, he said.

‘‘Whether it’s passing zero carbon legislatio­n, fixing the emissions trading scheme, or supporting public institutio­ns to switch to clean energy, we have been working to avoid worst impacts of climate change since the moment this Government formed,’’ Mr Shaw said. — RNZ

NEW Zealand’s first national climate change risk assessment makes for worrying reading about what may be a slowly unfolding national crisis.

Some of the 40odd risks are wellknown and have been taxing those long concerned about how our natural and built environmen­ts will cope in a rapidly changing world.

Its impact on potable water supplies, on regional infrastruc­ture and on lowlying buildings are obvious inclusions on the shortlist of longterm problems. So, too, are the risks to ecosystems due to sealevel rise, extreme weather and from the spread of invasive species.

Other areas might not have been immediatel­y obvious to anyone other than those who spend time understand­ing the knockon effect of significan­t, costly change.

It identifies threats to social cohesion and community wellbeing from displaceme­nt, and of the exacerbati­on of inequity due to unequal distributi­on of climate change impacts. It also identifies the massive costs associated with lost productivi­ty, disaster relief spending and unfunded contingent liabilitie­s.

Even the financial system could be affected by the instabilit­y arising from extreme weather events and the costly impact of tackling ongoing, gradual changes.

The list worsens as one reads on, as does the sense we are struggling to meet the risks headon.

The assessment says there is a risk of maladaptat­ion due to the applicatio­n of practices, process and tools that do not account for uncertaint­y and change over long timeframes.

Climate change’s impacts, it says, will be exacerbate­d because current institutio­nal arrangemen­ts are not fit for climate change adaptation.

The assessment challenges the Government but this does not mean the Government will — or can — provide the silverbull­et solutions the crisis may well need.

After all, the Government does not form all floodwalls or stopbanks. It does not plan subdivisio­ns, urban water systems or stormwater drains. It leaves the doing to others: regional, city and district councils are at the pointed end of the response.

Councils are in charge of the emergency responses and policy directions that have the most obvious, immediate and longlastin­g effects on the local impacts of climate change.

They each make their own decisions as to how their districts should develop in light of climate change, and how they and their communitie­s should respond to its most pressing effects.

They have their own policy frameworks which they develop in response to local concerns. They are helped by science and shared guidelines, but their policies are up to them.

Over the past five years, there has been a sense our towns and regions have been left to tackle the local effects of climate change on their own. Inconsiste­ncy has been a result.

The Dunedin City Council has a climate change adaptation plan and Mayor Aaron Hawkins has been clear in the need for climate change to factor in its decisionma­king.

Meanwhile, West Coast Regional Council chairman Allan Birchfield said climate change was a ‘‘rort’’ as his council digested a summary of the many hazards its region faced.

Such ‘‘political inconsiste­ncy’’ is par for the course in a democracy but having the tools to fathom what might seem unfathomab­le can minimise the risk this might pose.

Local Government New Zealand president Dave Cull says central government must now provide a framework enabling councils to increase their response to the ‘‘hyperlocal’’ but, cumulative­ly, nationally significan­t threats that come with climate change.

The Resource Management Act does not explicitly allow for climate change adaptation. The Act may be replaced, and it is hoped climate changeread­y policy will be quickly developed in its place. Until then, councils will continue to do as best they can, with the tools they have, in lieu of a unified policy response to local examples of a national — global — problem.
